PERCY WI; VALENTINE, OF NATICK, MASSACHUSETTS ATTAOHZAIBLE RIBBING FORINNERSOLES AND INNERSOLE EQUII PE D THERCEWITH Application filed.October 18,'1828. Serial No. 313,252.

This invention relates {to material for attachment to innersoles toprovide the rib in which the stitches of the inseam are placed forsecuring the upper, innersole 5 and welt together in the manufacture .of

welt-shoes. It has long beenacoinmonpractiee to make innersole-bodiesout of leather of inferior quality, leather-board, andother materialswhich a-re either not strong enough '1 or not thick enough to permit ofthe stitch .20 thereof through which the stitches" are passed in.attaching the rib to the body of 'the:sole.' V

The ribs so formed are usually rein-forced,

either by asepa-rate strip of material placed betweenthe folds of thefabric forming "the rib proper, or by an integral part of the fabricstrip folded back under one of the *attaching 'flanges and turned up atits edge int'o'the rib proper. Both of-fthese modes of reinforcementprovide three thicknesses of material in the rib, and the second onealso makes one of 'the attaching flanges a two-ply structure. Bothrequire material in excess of that 'neededto-make merely the rib properand itsfianges, and alsoa'special operation, that of placing thereinforcing strip or fiap properly within'ithe rib, and the ribbing o fboth-these descriptions which is made as a finding for sale to shoemakers, 0 is stitched at the base of the ribproper to hold-therib-inshape and the reinforcement in place.

My object is to provide a manufactured textile'rib or-ribbing for theuse above indicated, containing in its 'woven "structure means forsecuring together the plies which make the sides ofithe rib proper,andthereby reinforcing the rib. Secondary objects resulting from the"foregoing are the 'saving immaterial andlabor througheliniination-ofreinforcing material and of the operations of foldingthe rib andstitching its sides together; and the formation of non-raveling edges onboth flanges of the rib.-

The invention comprises a new ribbing for the purpose specified which iswoven with binder threads or yarns passing back and forth between theplies of the rib proper and having selvages :a't the edgesof bothflanges; and it further comprises a complete innersole consisting of abody combined with an attachedrib 0f the character above set forth.

In the drawings, v

Fig. l is a plan view, and Fig. 2 a crossi651 section on line 2-2 ofFig. 1, of an innersole embodying the present invention;

W Fig. dis a perspective view on an enlarged scale of afragmentofTibbingmaterial embodying this invention; Pg. 4 is a cross-section on line 44of Fig. 3, drawnon a still larger scale illustrating the wovenconstruction of'the material; h ii) Figs. 5 and 6 arelongitudinalsections on lines 5-5 and 6- -6, respectively, of Fig. 4,further illustrating the construction.

7 The innersole comprises abody wand an applied strip of ribbingmaterial having a ribproper b and flanges or flaps c and d, which areattached to the body by sewed seams-e, f and-g. In the elements and modeof connection thus far described, the present invention does not differfrom articles of the prior art. Its novelty consists in the structuralcharacteristics of the rib, and in the new combination comprised by theunion of such novel rib with an. inners ole body which may be eithernew'or .old.

Referring now to the structural detail views, Figs. 4, 5 and 6, theribbing material is seen to be a woven fabric consisting of warp threads1, l, andweft or filling threads .2. The rib 6 consists of anintermediate part of the fabric doubledto form two plies whichlie-contiguous to one another and are securely held in that relationshipby binder warps 3, 3.

V The binder warps are interwoven with the filllng threads in the courseof original manufacture of the material. By a suitable arrangement ofwarp threads and harnesses, the shuttle thread is caused to pass betweenthe warps of the flange (Z, for instance, and the adjacent ply of therib proper, then reverse, to pass between the warps of the op posite plyof the rib proper and those of the flange c. 11 again reversing, withchange of the sheds, the filling thread passes in the opposite orderbetween the warps of the flange c and the adjacent ply of the ribproper, and then between those of the other ply and the adjacent flanged. During weaving, of course, the flanges o and (Z are parallel to oneanother. The binder warps are placed in a width sufiicient to tietogether the two lies thus woven for a width equal to the desired heihtof the rib proper, leaving them unconnected for the rest of theirwidth, and therefore in a condition to be separated and spread apart atright anles to the rib proper when applied to the 0d of the innersole.

e weaving method above described is not my invention and is not claimedas such herein. But the application of this or any equivalent method tothe production of an innersole rib, and the ribbing material having theresultant characteristics, are my invention, for which I claim adequateprotection.

The article containing the characteristics above described has numerousobvious advantages, among which may be named the following:

The side plies of the rib, being tied together, not only throughout thelength of the rib but also at frequent intervals from base to summit,are not only prevented from separating, but are also reinforced andstiffened, each by the other. Thus the rib requires no additionalreinforcement to hold it upright when attached to the sole. The outeredges of both flanges are selvages, wherefore they will not ravel. Thisis a feature not possessed by ribbing made of strips cut from a sheet ofcloth, for both edges of all strips so out, except those out from theextreme edges of the sheet, are raw edges; and even the strips cut fromthe edges of the sheet are raw at one edge. These useful characteristicsare obtained with the utmost economy, for there is no separatereinforcing strip or cord, neither is it necessary to provide the stripwith excess width in order to provide material to fold back under one ofthe flanges and into the rib proper; and the additional operations ofplacing the reinforcement and stitching the sides of the rib togetherare obviated. Instead only the minimum of material needed to make a ribof given height with flanges of given widths is used, and the bindingtogether of the sides of the rib is performed in the course of weavingthe fabric.

What I claim and desire to secure by Letters Patent is:

1. An innersole comprising a body and a separate attachedstitch-receiving rib formed of textile fabric, having contiguous pliesforming the sides of the rib, and binder warps interwoven with fillingthreads of both lies.

2. n innersole comprising a body and a separate attachedstitch-receiving rib made of textile fabric; said rib having a ribproper formed of plies of the fabric arranged side by side and flangesprojecting oppositely to one another from the base of such rib, andincluding structural strands or threads interwoven with both plies.

3. Fabric ribbing for innersoles comprising a woven structure havingplies arranged side by side to form a rib proper and structural strandswoven back and forth between said plies in the rib proper.

4. Fabric ribbing for innersoles comprising a woven structure havingplies arranged side by side to form a rib proper and including binderstrands woven back and forth between said plies; one of the plies beingextended from the part in which said binder strands are located and fromthe other ply, to form an attachable flange.

5. A rib strip for attachment to innersoles having a rib proper andseparate attachin flanges at opposite sides of the base of sai ribproper; said strip being composed of a woven fabric doubledlongitudinally in its middle part to form plies extending side by sidebetween the summit and the base of the rib and including structuralstrands interwoven with both of said plies.

6. A rib strip for attachment to innersole bodies comprising a textilefabric having a warp and filling strands doubled lengthwise throughout aportion of the width of the strip to form a rib proper, and binderstrands interwoven with the crossin strands in those parts of both plieswhich form the sides of the rib proper.

7. A rib strip for attachment to innersoles, having a rib proper andattaching flanges at opposite sides of the base of the rib pro-per; saidstrip being a unitary fabric composed of interwoven warp and weftstrands and binder strands woven through the rib proper, and formed withselvages at the outer edges of both flanges.

8. A textile fabric rib strip for attachment to innersoles, comprising atwo-ply ribproper containing binder strands inter-' woven with bothplies thereof, and single ply flanges each being a part of one of saidplies.

9. A fabric stri 3 adapted to provide the stitch-receiving ri s ofinnersoles, compris ing textile fabric plies extending side by side andcontaining interwoven binder strands in a fractional part of theirwidth, which part constitutes the rib proper, and said plies beingotherwise unconnected from the rib proper to their outer edges andadapted to form flanges.

10. A fabric strip adapted to provide the stitch-receiving rib of aninnersole consisting of interwoven longitudinal warp and transverse weftor filling threads, the fabric so formed having selvages at both edgesand being of folded formation intermediate such edges to provide twoplies lying side by side from the fold; a part of the warp threads beingbinder warps passing back and forth between the wefts of said plies in aportion only of the width from the fold to the nearer selvage edge,forming thereby a rib proper; the plies of the fabric adjacent to saidselvage edges being separable from one another and providing flanges forattachment to the body of an innersole.

In testimony whereof I have aflixed my signature.
